Attention à la température de votre thé : elle pourrait favoriser certains cancers
## Impact of Hot Beverage Consumption on Health
Impact of Hot Beverage Consumption on Health
The consumption of beverages like tea and coffee is widespread globally. While these drinks are known for their antioxidant properties and potential cardiovascular benefits, it is crucial to consider the temperature at which they are consumed. According to the International Agency for Research on Cancer (IARC), consuming very hot beverages (above 65 °C) may be probably carcinogenic to humans . This classification highlights the importance of temperature rather than the beverage itself.
Studies conducted in various regions, including South America, the Middle East, Africa, and Asia, have shown a correlation between the consumption of hot beverages and an increased risk of esophageal cancer. Recent research from the UK involving approximately 500,000 adults confirmed this risk among Western populations. Individuals consuming large quantities of very hot tea or coffee had a significantly higher likelihood of developing esophageal cancer, with those drinking eight or more cups daily facing nearly six times the risk.
Ingesting hot beverages can cause minor burns to the esophageal lining, leading to chronic inflammation. This inflammation may facilitate cellular mutations, increasing the risk of cancer. Experimental studies have demonstrated that consuming liquids at 70 °C accelerates the development of precancerous lesions compared to cooler temperatures. Additionally, large sips of hot beverages can raise the esophageal temperature significantly, further exacerbating potential damage.
While these drinks are known for their antioxidant properties and potential cardiovascular benefits, it is crucial to consider the temperature at which they are consumed.
To mitigate these risks, it is advisable to allow hot drinks to cool for a few minutes before consumption, reducing their temperature by 10 to 15 °C. Small sips can also help maintain a safe esophageal temperature. An optimal drinking temperature is approximately 57.8 °C, which is hot but does not cause immediate burns upon contact with the tongue. Ensuring beverages are consumed within this temperature range can enhance safety without sacrificing enjoyment.
Regularly consuming very hot drinks increases the risk of esophageal cancer. Repeated thermal exposure can damage the esophageal lining, promoting cellular mutations. Allowing drinks to cool and avoiding large sips can reduce potential harm.
